The invention relates to coke ovens having vertical heating iiues in thewalls between the heating chambers with regenerators connected thereto,one for each ue or for a group of fiues,.

so that the gas volumes diier very considerably.`

That of the waste gas may be twice as great as that of the air and fuelgas. There are valves or dampers for regulating the ow of the gases toand from the regenerators, but in practice it is not possible to adjustthe dampers at each reversal,`so as to suit the inflow of air and gasand the outflow of waste gas alternately, and the general practice is tomake only rsuch adjustments as may be required to suit varying volumesof waste gas. The result is that the effective openings for the passageof gas are practically always much larger than is required for theadmission of the air and fuel gas, so that regular distribution of theair and fuel gas to the regenerators is not obtained. y

According to my invention this defect is overcome by subdividing thedistributing sole chan-v nels by means of a horizontal partition havingregulatable openings; the air and fuel gas being admitted to the lowersections of the channels, and the upper sections being in communicationwith the regenerators by means yof the usual valve or damper controlledopenings and having also a valve controlled outlet to the waste gasmain. Each lower section may also have valve controlled communicationwith the Waste gas main. With this arrangement the air and gas, beforepassing through the openings admitting them to the regenerators, passthrough the regulatable openings in the horizontal partition, and thesecan be adjusted to suit the\volume of air and gas, and secure properdistribution thereof, irrespective of the adjustment of the valves ordampers at the openings of the regenerators, thesey being adjusted asusual to suit the periodic outflow of waste gas.

An embodiment of the invention is shown in the accompanying drawing, inwhich:

Fig. 1 is a vertical section of such part of the oven as is required forillustrating the invention, the section being taken on the line E-F ofFig. 3.

Fig. 2 is a cross-section on the line A-B of mfr 1 ovv! Fig. 3 is ahorizontal section on the line Cv-D of Fig. 1.

Each bank of vertical regenerators has below it two horizontal solechannels divided *by a horizontal partition 2 4into two sections, thusforming a pair of superposed sections a, a1 on one side of the verticalydividing wall and a similar pair b, b1 on the other side. The oors ofthe regenerators have openings 4, 5 controlled by dampers B, forcommunication with the upper channel sections a, b, and the partition 2has openings 1, 8, controlled by dampers 9, for communication with thelower channel sections ai, b1. The four channel sections a, ai, b, b1communicate at each end by means of pipes i0 having valves Il thereinwith a stack or waste gas flue I2 extending transversely of the banks ofregenerators. The

construction being the same at each end, only one end is shown in thedrawing. A gas main I3 supplies fuel gas through pipes I4 with valvesIda. to each lower section a1, and air is supplied to each lower sectionb1 through conduits I5 (Fig. 3). These air conduits have valves like thevalves Ma of the gas conduits and may be connected thereby to an airmain, like the gas conduits I4 are connected to the gas main I3. Theopenings 4, 1 and the openings 5, 8 are vertically in line with eachother, and the roof of the passages I6 in the base of the oven ispierced with short shafts I1 vertically below the openings, so

that a workman walking along the passages canhave access to all thedampers, by means of a bar pushed through the walls.

What I claim as my invention and desire to secure by Letters Patentofthe United States is;

1. A coke oven comprising a bank of vertical regenerators, two solechannels extending lengthwise of the bank below the same and arranged tocollect and carry off waste gasesfrom and to distribute fuel gas and airto said regenerators in alternate heating periods, horizontal partitionsY dividing said sole channels into upper and lower sections said upperchannel sections communieating with said regenerators through regulableopenings and said partitions having regulable openings therein forcommunication of said low--` er channel sections with saidregenerator'af.y

valved means for supplying fuel gas to one 'and air to the other of saidlower channel sections, a stack flue, and valved means for'connectingboth said sole channels to said stack flue.

2. A coke oven according to claim .1, in which Y JOSEF scHm
